Researchers at the University of Massachusetts (UMass) Amherst and the Lisbon-based Catcher project are exploring the potential of generating electricity from air humidity. The UMass team accidentally discovered that an array of nanowires produced an electric signal when exposed to air. They have now developed a device with nanopores that can generate a small amount of electricity, which can be increased by stacking multiple layers.
The Catcher project has also made progress in generating electricity from atmospheric humidity and aims to commercialize the technology. While the technology shows promise, challenges remain in scaling up production and reducing costs. Despite these challenges, experts are optimistic about the potential of this technology, which could provide a continuous and renewable source of electricity day and night, indoors and outdoors.
